DEVICE FOR HEATING WATER.

Patented June 2, 1914.

To all whom it may concern Be it known that I, CHARLES B. ELMER, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Devices for Heating WVater, of which the following is a specification.

My invention relates generally to that class of water heating devices in which the heat is applied to a water containing passage, as a coiled pipe, and the object of my improvements is to enable the utilization of kerosene oil as the heating agent'for this purpose. I

While kerosene provides a cheap and abundant fuel, it has not heretofore'been' utilized in connection with such devices for heating water, for the reason that the maximum size wick which can be practically employed in a kerosene burner does not give a flame of sufiicient size to supply the necessary amount of heat, and no practically suc cessful means has heretofore been devised for so combining the heat of a plurality of flames as to effect the desired result.

My present invention comprises an ar rangement of a plurality of burners each having an individual chimney, such that the heat of all the burner flames may be efliciently and conveniently utilized in the heating of a water supply.

An embodiment of the invention is illustrated in the accompanying drawings, of which Figure 1 shows a side elevation of a heating device attached to a water tank or boiler; Fig. 2 shows a vertical section with the stove and hood removed; Fig. 3 shows a front elevation of a stove with the hood thereon; Fig. 4 shows a section on line M, Fig. 2; Fig. 5 a view in perspective of a spreader located within the heating coil; and Fig. 6 shows a section on line 66, Fig. 2.

Referring to the drawings, A, indicates a kerosene stove, of any usual or suitable construction, having a plurality of blue flame, or smokeless, burners, each of which is surrounded by the usual chimney, B, B. The upper ends of the chimneys, B, B, engage with a hollow metal hood, 0, the lower end of which is preferably so shaped and proportioned as to include and fit the chimneys, B, B, and which is drawn inward upwardly so as to assume a cylindrical shape at its upper end. Above the hood, 0, is a metal collar, D, the lower edge of which, when the stove, A, is in position for operation, engages e teriorly the upper end of the hood, U. The collar, D, is provided with a door or hinged portion, d, the opening of which enables the hood, C, when in position on the stove, to be conveniently moved into or out of engagement with the'collar, D, which is held in fixed position on the water pipe, E, leading from aboiler or tank, F. The pipe, E, 1S connected with the lower end of a heatlngcoll, G, from the upper end of which a pipe, H, leads into the upper part of the water tank, F. Within the heating coil, Gr, 1s a metal disk, or spreader, 9, whereby the gaseous currents are brought into more intimate contact with the coil, G. The heating 0011, G, is inclosed within a vertically movable shell or casing, I, which is supported by the upper edge of the collar, D. For the purpose of conserving the applied heat, the casing, I, may be provided with an upward extension, J, of smaller diameter, which surrounds the water pipe, H, and the lower part of which telescopes within theupper part, K, which may be secured to pipe, H, v

by a set screw, 70.

When the oil stove is in operation, the products of combustion from the stove burners are discharged through the chimneys, B, B, into the hood, G, and thence into the casing, I, which forms therewith a common passage for the products of combustion. Thus the water in the coil, G, is subjected to the heating effect of both burners, and is rapidly heated.

While I have shown an oil stove having only two burners, a greater number of burners may be employed, if desired, with a correspondingly greater heating effect, the base of the hood, 0, being in that case shaped and proportioned to include the chimneys of all the burners employed.

When it is desired to remove the stove, as for purposes of cleaning or otherwise, it is only necessary to open the door, (Z, when the stove with the hood, C, may be moved away, and in the same manner readily replaced when required.

The advantages of my invention will be readily apparent to those skilled in the art, since it affords a simple and inexpensive means of heating the contents of a water boiler With an economical and readily obtained fuel, and which can be easily in stalled in locations Where gas as a fuel cannot be had, and at much less expense than a hot Water back range.

What I claim as new and desire to secure by Letters Patent is:

1. The combination With a blue flame kerosene stove provided With a plurality of burners, of an individual chimney for each burner, a hood forming a common continuation of the burner chimneys, a fixed collar arranged to engage the upper portion of said hood, a vertically adjustable casing arranged to rest upon said collar, and a Water heating coil arranged to be connected With a Water containing vessel and located Within said casing.

2. A Water heating device comprising a blue flame kerosene stove provided with a plurality of burners, individual chimneys for the burners, a hood arranged to engage the tops of the chimneys of all the burners,

and forming part of a common duct leading therefrom, a collar arranged to separably engage the upper portion of said hood, a casing engaging With said collar, and a Water heating coil arranged to be connected With a water containing Vessel and located Within said casing.

3. The combination With a blue flame kerosene stove having a plurality of burners and individual chimneys therefor, of hood, C, collar, D, and casing, I, forming a single continuous passage from said chimneys, and a Water heating coil inclosed Within said passage and arranged to be connected With a water containing vessel.

In testimony whereof, I have hereunto subscribed my name, this 6th day of January, A. D. 1910.

CHARLES B. ELMER.
